GREGORY DUORO, OF BUFFALO, NEW YORK.

BOTTLE-STOPPER.

SPECIFICATION forming. part of Letters Patent No. 270,765, dated January 16, 1883.

Application filed November 4,1882.

To all whom it may concern 'Be it known that I, GREGORY DUGRQ, of the city of Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Bottle'Stoppers, of which the following is a specification.

This invention has reference more particu larly to that class of stoppers for bottles, fruitjars, and the like in which the mouth or neck of the bottle or fruit-jar is provided with inclined ledges or shoulders on its outer surface, and the stopper provided with a bail or clamp, which engages with said inclined ledges, and by means of which the stopper is firmly clamped or secured to the mouth of the bottle.

My invention has for its object to improve the construction of this class of stoppers; and it consists in the particular construction of the stopper which will be hereinafter described, and pointed out in the claim.

In the accompanying drawings, Figure l is a side elevation of my improved stopper, and

Fig. 2 is a sectional elevation thereof. Fig.3

is atop plan view of the mouth of the bottle with the stopper removed. Fig. 4. is a bottom plan view of the stopper.

Like letters of reference rt-ler to like parts in the several figures.

A represents the upper portion or neck of a bottle or fruit-jar, and a d are two ledges or shoulders having inclined lower sides, a, and applied to the outer surface of the bottle or jar below its mouth, and separated by vertical what narrower than the slots a so that the lugs can be readily passed through the slots in applying the cover to the bottle orjar. The top I) of the cap B is preferably cast solid and provided with a screw-threaded hole, 0, in which is inserted a thumb-screw, D, which substantially as set forth.

(No model.)

the cap B.

fis a rubber washer arranged below the metallic washer e and bearing against the mouth -of the bottle. The rubber washer f is made 5 large enough so that when inserted in its place inthe cap B it will retain the metallic washer e in its proper position and prevent it from falling out.

The cap or cover B is readily secured to the bottle by passing the lugs b through the slots (1. until the lugs reach the inclined shoulders or, when, by a slight turn of the cover, the lugs b wedge themselves against the inclined lower sides, a, of the shoulders or. and firmly hold 6 the cover in place. The rubber washer fis thereby compressed between the mouth'of the bottle and the top of the cover, and the mouth of the bottle or jar is tightly'closed. Upon tightening the thumb-screw D against the meby the wedging action of the lugs and in- 7 clined shoulders. The cover B forms a rigid connection between the lugs b and the other operative parts of the stopper, and enables the bottle or jar to be tightly closed without danger of leakage by the yielding of the cover.

Upon removing the cover and the washers the month of the bottle or jar is entirely unobstructed, and its contents can be removed, and when empty it is easily cleaned. The

cover B, when applied to the bottle orjar, in-

closes the shoulders a and prevents breakage of the same.

I claim as my in vention- The combination, with a bottle or jar having its neck provided on its outer side with shoulo ders a ,inclined on theirlower sides, of a coverorcap, B, inclosing the neck or upper portion of the bottle or jar, and provided with lugs b, a threaded hole, a, screw D and washers e f,
